SYSTEM
Performance under
has been
improved by the introduction of Wind
Trim.
With Wind Trim the computer uses the
compass as the primary heading
reference. However, as changes occur in
the apparent wind angle the computer
automatically adjusts the compass
heading to maintain the original apparent
wind angle.
This system eliminates the effects of
turbulence or short term wind variations
and provides smooth precise performance
under
with minimum current
consumption.
When a
system is fitted, a
new layer of control functions is
automatically opened as follows:-
Push both red keys together once

degrees.
